At least 68 killed in Spanish high-speed train crash, as prime minister says ‘whole country is grieving’

At least 68 people have been killed and dozens more injured after a Spanish high-speed train collided with another train south of the capital Madrid

The updated death toll makes this crash the country’s worst rail disaster since 2013

Spain’s transport minister says an “inexplicable” decision by the control centre led to the collision after a computer failure initially caused trains to halt

The rail operator Iryo says its train was “struck from behind” by a Renfe train. More than 500 passengers were travelling on the two trains

Speaking at the crash site, Prime Minister Pedro Sánchez says Spain is “grieving” – most major parties have suspended general election campaigning

Sánchez also vows to find out “why this tragedy occurred” – here’s what we know so far about the cause

Witnesses have described “terrible” scenes, while Roberto Gómez, a Spanish journalist travelling on one of the trains, says it was “extremely chaotic and very distressing”
